Remember, driving is a privelidge, not a right.
i dont drink anymore, and i never drove after having even 1. but its amazing how many people think that just because it is not directly enumerated in the constitution it is not a right.
9th ammendment: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people
10th ammendment: The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
of course i should not be supprised, our 1st 2nd 4th and 5th ammendment rights get violated constantly....
